Solder Ring Copper Coupling Pre-Solder Type

Solder Ring Copper Coupling

• Description：Solder Ring Copper Coupling,Solder Ring Copper Capillary Coupling,Coupling-Staked Stop,Coupling-Rolled Stop,Coupling-No Stop with UPC,NSF61,WRAS ,SABS approval.
  As one type of end solder ring  fittings,first use coarse steel wool to clean the pipe ,cover the flux paste ,then insert the pipe to the fittings' socket.take the solder bar and heart together with the socket.It will be finished when a ring solder showed at the edge of the fittings.
  Our solder also confirmed with  SN99.3CU0.7.Actually,the lead of the solder in Runde is lower than 0.01%.Much lower than other suppliers.And our solder ring inside the socket are smooth.There has no bubble hole inside.
  The copper fittings known as copper pipe fittings ,copper pressure fittings and copper plumbing fittings, divided to End Feed Copper Fittings(wrot joint copper fittings ) and solder ring copper fittings(presolder copper fittings).And the  quality of our EN1254-1 copper fittings can compare with yorkshire copper fittings( pegler copper fittings ) and connex copper fittings .our ASME B16.22 copper fittings also has exported to Mueller in U.S. Here,The solder ring copper coupling are produced according to EN1254-1 and ASME B16.22 standard.And we have same end feed type for your selection.
